Have Samsung got an answer to this irritating issue? Intermittent and sometimes frequent "Network Cable disconnected" message followed by " Network Cable connected". My TV is a Q90R
I have been having similar issues for a number of years with my UHDTV 7 Series. The interesting additional problem (possibly connected to this problem) is that my TV has a brief black screen moment. It doesn't occur at the same time as seeing the Network Cable Disconnected but at "random" times. It has been happening for the past number of months. I don't know if the HDMI port or cable are defective. No idea how to test whether the current HDMI cable is reliable/effective.
The very latest firmware/software update seems to have improved this issue. It still happens but not so often. The network doesn't actually disconnect. I have noticed that when using other devices at the same time as watching TV, this issue can occur. I am beginning to think the issue is with routers or networks rather than a TV fault. Surely Samsung could update the software so that this option could be switched off, or reduce the sensitivity of whatever triggers the message.
It temporary loses the connection to the router.
I have no idea (aside lack of brains) why would anyone want to be notified about in an intrusive manner, given that the connection would automatically be restored shortly after.
The notification has zero practical value and it's a pure annoyance. Some bonehead product manager thought it'd be a good idea to see that.
Might be of interest. I have changed from Virgin Media to Talk Talk as my internet provider. This irritating message now seems to have stopped. Still using a wired connection. Which does suggest the issue is with the internet provider(s) rather than Samsung? Either way, Samsung could easily update the firmware with an option to disable this notification.
I am now certain the issue in my case, was with Virginmedia or more likely their router or router firmware. After changing to Talk Talk the issue has totally disappeared.
